grid heater cycling with warm engine
I wanted to know if grid heater is supposed to cycle when engine is restarted.Mine will cycle every time I restart it.It does't time when key is turned on but will cycle till 20 mph. or whatever other parameter it uses if you don't attain ground speed.

Mine is the same way, and sometimes it will cycle when its warm outside and I'm on a restart. Look at it this way, it's cycling your batteries and giving your alternator a workout.

Totally normal!
The only time I've seen the truck start without cycling the grid heater is in the middle of the summer a really hot day.
Just make sure you give it enough time to recharge the batteries. I try to drive a min. of 5 miles to be sure or leave it idle with the jake on...

Turning off the ignition then restarting, regardless of the in between time will cause the grid heaters to start to cycle again. I forget offhand what the outside air temperature must be for the grids shut down. 56 degrees or something like that. It has nothing to do with engine temperature. It's outside air temperature.

Makes for better air flow.
Most who have removed them don't drive their trucks daily, or in cold climates.
Like sledpullers or drag racers.
Some company makes an aluminum block that takes their place.

practical solutions makes a heater grid saver to eliminate this problem. I have one on my truck and it works great.
Another solution would be to disconnect the lead from the battery on the drivers side for the heater grid. Do not disconnect the lead from the heater grid or you could have the fourth of july under your hood. Always disconnect from battery, samll nut on bolt going through battery clamp. I use to do this but got tired- lazy so bought the practical solution one.

Easier way to disconnect the grids is to pull the one small wire off the heater relays a little to the rear under the driver's side battery. They just slip over a post, 5 second job.

What is the minimum temp that you can go to without the grid heater for cold start?
Is there any problems with disconnecting it?
Morning temps around here are about 25*F - 45*F lately...
I normally let the grids heat for the first start of the day. The rest of the day I don't even wait for the light to go out... I just "KICK THE PIG"...
I would rather lose the load of the grid heater hitting the alternator every start. Speed limits in town are 15 - 25 MPH so it kinda hard to shutdown the grid heater at times... Some dayz a lot of short trip in town...

Best bet is to experiment to see how much smoke you can handle.
Never tried it but my guess is it would take a lot of cranking to get a truck to start with no grids once the temp drops below 25°.
